I'm pretty sure this will be in my notes that I haven't quite gotten to yet, but the question came up and I'm antsy to satisfy my curiosity

Ion-ion attractions.

I'm sure I'd catch this if I studied on, but I'm anxious
Wouldn't the positive and negative charge of the cation and the anion cancel each other out and form a neutral compound? What is left to cause a
charge attraction?
is it that as an electron leaves sodium and goes to chlorine it become + and the chlorine becomes negative, when they are combined as a compound? With
opposite charges which causes them to be neutral, but then have charged ends?

Opposite charges attract.
I suggest you read your textbook. It really is not that difficult. But it will be easier for you to isolate the particular point that you are
stumbling on through thorough reading than it will be to thrash it out on a message board. In any case, questions like this one are ideally suited to
the short questions thread.
I recommend this video. I get my students to watch it multiple times. It is well scripted and every word is important. By the time you get to the
point where you can nearly quote it, you will have a pretty good handle on the situation.
